DP83TC811SEVM：テストモード変更方法

Hi, 

Are you able to read/write registers? You can find our USB-2-MDIO guide here. 

Please refer to 8.3.3.5 Built-In Self-Test, 8.3.3.6 Loopback Modes, and 8.3.4 Compliance Test Modes of the DP83TC811 datasheet for details on how to change the test mode of the PHY. 

Thanks,

David

連絡ありがとう。

USB-2-MDIOを利用してレジスタの読み取りは出来ますが、書き込みができません。

0836を読みとり後、0010のデータを書き込んでも0000が読み取れます。

書込み方法を教えてくれますか？

Hi, 

You are writing the incorrect value to register 0x0836, and attempting to write to read only bits.

To enable test mode 1, you should be writing 0x2000 to register 0x0836. 

Please see Appendix A of the following report for how to enable each test mode: https://www.ti.com/lit/an/snla276/snla276.pdf

Thanks,

David
